Overnight Road Closure Continues for I-680/Mission Boulevard Interchange from March 30 through April 3

As part of the restoration activities following
the Bay Division Pipeline installation, the contractor is required to restore the freeway on-ramps the
way they were found prior to the start of construction. In order to complete
this work, overnight work is necessary.

Beginning on Monday, March 30
from 12 a.m. to 5 a.m., the contractor will require overnight on-ramp closures
to the cloverleaf northbound on-ramp of I-680 from eastbound Mission Boulevard.
These closures are needed in order to remove temporary water pipes and fill in
open trenches, now that the main Bay Division Pipeline installation is
complete. This work will continue on Mission Boulevard during the day and some lane
closures will be required. Please be mindful of posted traffic and detour
notices.

Approved
Work Hours/Road Closure Hours:

Estimated Work Dates:
Nightly, from 12 a.m. to 5 a.m. beginning on Monday, March 30, for up to four
consecutive nights (until Friday, April 3 at 5 a.m.)

Road and on-ramp
closure hours: midnight to 5 a.m.

The contractor
will require an hour of set-up time prior to the on-ramp/road closures. Work
hours may start as early as 11 p.m. nightly.

To alleviate traffic-related concerns during major
commute hours, this on-ramp work requires up to four nights of consecutive overnight work.

Substantial
completion of this project is anticipated for May 2015.

Are you Prepared for the next Earthquake?

The Hetch Hetchy regional water delivery system is taking steps to seismically reinforce its pipelines, tunnels and other facilities and we encourage you to be PREPARED. Check with your County or 72hours.org about how you can get ready. Remember, store at least a gallon of water per person, per day—enough to last 3 days, for drinking, cooking and personal hygiene—and don’t forget your pets.

Project Information

The Seismic Upgrade of Bay Division Pipelines Nos. 3 and 4 (BDPL 3&4 Seismic) is part of the San Francisco Public Utilities Commission’s Water System Improvement Program. This project will seismically upgrade two drinking water pipelines where they cross the Hayward Fault in Fremont. To protect the water system, the BDPL 3&4 Seismic project is replacing large sections of the pipelines with high-tech pipe elements and structures designed to protect them from damage during a major earthquake.

The pipelines, known as Bay Division Pipeline Nos. 3 and 4, cross the Hayward Fault near the intersection of Mission Boulevard and I-680 in Fremont. All project work will take place within the SFPUC’s right of way and nearby staging areas.

The seismic upgrade of Bay Division Pipeline Nos. 3 and 4 will improve the reliability of the water system for the Hetch Hetchy Regional Water System’s 2.6 million customers in the Bay Area, including Alameda County.

Our project team is working closely with local officials to ensure construction schedules are timely and traffic and community inconveniences are minimized.

Our Goal

It is our goal to provide timely, useful information on the Seismic Upgrade of Bay Division Pipeline Nos. 3 and 4 throughout the duration of the project. As construction continues, check back for construction updates, work schedules and traffic impacts in Fremont.
